The Defender (ディフェンダー, Difendā?; or 守りの剣, Mamori no Ken?, lit. Protecting Sword), also called Defend and Defense, is a recurring knight sword in several Final Fantasy games. It usually raises the user's Defense stat or helps protect them in some way.

Due to the critical hit bug found in the original versions, the Defense sword is technically the most powerful weapon available to the Red Wizard, assuming the Masamune is given to a different character. Although the Red Wizard can also use the Sun Sword—which has slightly higher attack power—the Defense sword's high critical rate will ensure it inflicts a greater degree of damage per hit.
